Title: Improvements in or relating to electric telegraph receiving systems
IPC: H04L15/26
Filed: 1935-03-25
Abstract: 454,021. Selectors. WATANABE, Y., 7, 4-Chome, Kinukake-cho Suma-Ku, Kobe, Japan. March 25, 1935, No. 9280. Convention date, June 20, 1934. [Class 40 (i)] The selector described in Specification 436,343 in which a received Morse-code signal is registered by the displacement of contact-controlling rollers along the bars of a rotary squirrel-cage construction, the reception of certain predetermined signals causing the operation of characteristic alarms, is modified by providing each bar with two rollers, the position of one of which indicates whether a particular received impulse was a dot or a dash, while that of the other indicates whether or not it was preceded by a space. By this means it is made unnecessary to advance the squirrel-cage for spaces and the diameter of the cage necessary for registering any given signal is thus reduced. Construction. The rollers, which control contact springs 51 &c. on a fixed frame, are brought by guides 11, Fig. 3, into their normal tracks before they reach the displacing mechanism which comprises star-wheels 13, 13<1> driven step-by-step by " dash " and " space " magnets respectively. Dots cause the advance of the squirrel-cage without the displacement of a roller. Circuit arrangements, Fig. 11. In the absence of signals, C3, C4 and the space magnet F are energized. When a marking signal arrives, C1 energizes the driving magnet D of the squirrelcage and, if the signal has a sufficient duration, C2 operates and energizes the " dash " magnet E which energizes G. G locks up until a new signal arrives, whereupon H releases it. The contacts of G thus register the last signal received and are used instead of fixed roller controlled contacts in one of the roller-displacing positions of the frame since such contacts would be difficult to fit. The final space is similarly registered by the springs t8 on the space magnet F.

Patent GB-960663-A (GB)
Title: Improved process for the purification of bismuth
IPC: C22B30/06
Filed: 1962-03-13
Abstract: Bi is purified by heating the impure material under a vacuum and at a temperature such that only impurities more volatile than Bi are distilled off and then raising the temperature and pressure to distil only the Bi and leave the less volatile impurities as a residue.  In the first stage the Bi is preferably heated to a temperature of 500-620  DEG C. under a vacuum of 10-1 -10-2 mm.  Hg. and in the second stage the pressure is raised to 1-4 mm. Hg. and the temperature increased to 720-750  DEG C.  Both stages may be repeated to produce ultrapure Bi. If the starting material has a purity less than 99.5% it may be given a preliminary purification by dissolving the initial material in nitric acid, adding diammonium phosphate to precipitate bismuth phosphate, converting the phosphate to oxide with caustic soda and reducing the oxide to Bi in pure hydrogen.

Title: Improvements in or relating to Path-Seeking Networks
IPC: H04Q3/00
Filed: 1968-02-29
Abstract: 1,157,778. Automatic exchange systems. SIEMENS A.G. 29 Feb., 1968 [1 March, 1967; 27 Dec., 1967], No. 9772/68. Heading H4K. In a switching system through which routes are selected by means of a path simulation network, a fault detector is connected to the guide wires of the simultation network in order to ensure that just before switch-through of a selected route only one wire is marked at each stage and then after switch-through that no wires are marked at each stage. Fig. 1 depicts the guide wire network between marking centres K1, K2 of one stage and marking centres K3, K4 and K5 of the following stage. After one free path has been selected, the marker causes the connecting relays pertaining to this path to come up and in so doing they operate one of their contact sets. For the two stages considered here it is assumed that it is the connecting relay B1 which comes up and thus makebefore-break contact set 1b1, 2b1 operates to connect a fault detector P to the guide wire incorporating decoupling rectifier G1. P receives a single pulse on one wire I if all is well. If however a rectifier has broken down or there is a short circuit between guide wire " G1 " and any other guide wire or the coupling relay does not operate, then P receives a plurality of pulses or a permanent potential or no pulses and consequently the marker recognizes a fault condition. It thereupon operates an alarm and switches the faulty section of the simulator out of circuit. In an alternative embodiment, the fault detector is connected to the guide wires by an auxiliary relay, the operation of the coupling relay (and consequent opening of its guide wire contact 2b1) being delayed-as by slugging (Figs. 2 and 3, not shown).

Title: Improvements in and relating to high frequency electric cables
IPC: H01B11/18
Filed: 1936-04-02
Abstract: 472,696. Cables. SIEMENS & HALSKE AKT.-GES. April 2, 1936, Nos. 9790 and 9791. Convention dates, April 17, 1935 and Oct. 30, 1935. [Class 36] In a high-frequency cable having one or more tubular conductors or screens formed of a number of thin highly conductive metal bands stranded in side by side relationship with a long lay, to prevent displacement over one another of the adjacently located bands within a stranding layer, the bands are reinforced at their edges, or over the whole or major part of their width, to an extent which makes the thickness of the reinforced band equal to at least twice the thickness of the actual band. The reinforcement of the bands may be effected, as shown in Fig. 1, by doubly folding the edges of the band, or by sticking a metal, paper, or polystyrol strip 11, Fig. 2, to the back of the band 10. The strip 11 may be narrower than the band 10, and the edges of the band may be bent over the edges of the strip. Fig 7 shows a twin conductor air-space cable having a screen 35 consisting of a stranded layer of metal bands each reinforced by a backing strip, the edges of the bands being bent over the edges of the strips. A coaxial conductor cable having the outer conductor formed similarly to the screen 35 is also described. In the construction shown in Fig. 8, the outer conductor of a coaxial cable is formed of thin metal bands 42 combined with profiled iron or insulating strips 43, which are so shaped that the edges of adjacent band interlock in a radial direction. In a modified construction the profiled strips are of the shape shown in Fig. 11, and are secured together by round wires 52 which are located in grooves formed in the edges of the strips.
